' Fig. =7 is a perspectiveview of the locking ring used with 'the'=valve shownin-Fig-JG. As" shown in: {F igs. 1 and 2 thB-vahecomprises a valve body 1 in whicha'valve member 221s rotatably mounted-and adaptedto be turned-through an arch of :ninetydegrees; to

member '2 is provided with aportion '3 :of

smaller diameter and a portion-4 immediately thereabove which is substantially square in cross section. The valve 'body adj a'centthe upper end is provided with a pair of diametrical-1y opposite ground oft portions orflat faces 5 and these ground portions :5 are flat while the remainder of theaval-ve body at the upper edge iseylindrical in form; A lockingringfi is provided having an: opening/Tinlthe bottom.

and this opening is provided with 'twofiat sides8 which are adapted to fit over the flat ground portions 5 on the valve body. )The ring 6,=-asshown in Fig'fis also-provided "-with a square aperture" 9 fitting the faces of the'square portion 4 ofthe:rotatable valve member. 'The lockin g ring 6 is shown in locked position in'Fig-Q andin the-unlocked position in Figs 1. When-the valve isinthelocked position shown in Fig.2 the ring may be :lifted to bring the loweredge thereof above the upper edge ofthe-valve 'bodylat'which time the handle 10 may-be turned to open the valve. As the handle-l0 is turned the portions 8 of the ring, shown in Fig. 4, res't on'the upper-edge of the=valve body as shown in Fig. 1, and the ring G will remain in the raised-position as long asthe valve is open.- As thevalveis again turned ":to the closed position'thering rides around on-theiupper edge ofth'e valve body until the vflatportionsS of'the ring come to alignment ewithithe flat'faces 5 "or the valve body "at whichtime the =ring will drop ;-by gravity to V g v f thelocked position. Due tOL-the ringfittin'g 45 arm-g 11SB;d3l Vlth;bh6IV&l:VB formeshown'in-Fig3,

the squarev portions 4 of'the rota-table valve member it is prevented from rotation in relation to the valve member but at the same time may be moved longitudinally thereof and when the ring portions 8 engage the portions 5 on the valve body the ring is prevented from rotation in relation to the valve body and also prevents rotation of the rotatable valve member. 7

In the form shown in Fig. 3 the flat face 5a is carried out on a taper instead of being broughtto an abrupt end as shown inFig. 1 and the rotatable valve member portion 4a instead of being square is provided with two diametrically opposite flat faces 11. The

locking ring 12 for this form of valve isshown more particularly 'in Fig. 5 and is provided with two flat faces 13 for the companion faces 5a of the valve body and withtwo flat faces 14 for the flat faces 11 of the rotatable valve member. The operation with this form of the device is exactly the same as the form shown in Figs. 1, 2 and 4 and has the advantage that less machine work'isrequired to form the various parts.

H In the formshown in Fig. 6 the valve is reversed in, position and the valve body is provided with two diametrically opposite flat faces 15 and the locking ring 16 is provided with two'flat faces17 which always engage the fiat faces 15 of the body and the ring 16 is movable up or down on the valve body. The rotatable valve member 18 is provided with two diametrically opposite fiat faces 19 and the ring 16 is formed to fit the rotatable valve member 18 and the flat faces 19 when the valve is turned to closed position. 7

In the position shown in Fig. 6 the handle I has just been turned to turn the valve to the the ring 16 will drop down over the portion 18 and lock the valve from rotation. The

- member 18 is provided with a flange 20 which provides a stop for the ring 16 and the ring to open the valve.

From the foregoingdescription it becomes evident that the device is very simple-and eificient in operation, will not add greatlyto the expense of the ordinary gas valve and provides a device which accomplishes the objects described.

Having thus fully described my invention,

its utility and mode of operation, what I claim and desire to secure by Letters Patent of the United States is g 1. In a valve for gas ranges, a valve body provided with a flat side adjacent the end of the body, a valve member rotatably mounted in the body and also having an extending -;-port1on thereof flattened on one s'ile, a lock.-

ing ring longitudinally movable on the valve member to engage over the end ofthevalve body, the inner wall of whichring is formed with a flat surface fitting the flat face of the valve member and further having an additional flat portion adapted to fit over the fiat face of the valve body, the said valve body having an upper end on which the locking ring may ride when moved out of engagement with the flat face of the valve body and the ring being adapted to engage over the flat face of the valve body when the flat face of the valve member is in alignment there with thereby releasably holding the valve member from rotation.

2. In a valve for gas ranges, a valve body having the side adjacent the end formed with valve member when the valve is open and being further formed with an additional flat portion adapted to engage with. the flat face of the valve body when turned to alignment therewith.

' 3. In a valve for gas ranges, a valve body having the side face thereof at the end formed with a flat face, a valve member rotatably mounted in the body and projecting therefrom, the projecting portion of the valve member having a fiat face on one side, alockmg ring havlng an aperture'fitting over the valve body and having a flat face fittingthe said fiat face of the valve body, said ring 7 also being movable longitudinally of the pro ecting end of the valve member and having an additional flat face fitting the said flat face of the valve member and holding the valve member and'body from relative rotation when the respective flat faces of the body and valve member are in alignment;

4. In a valve for gas ranges, a valve body having the outer surface thereof adjacent the end formed with a flat portion, a valve member rotatably mounted in the body, a locking ring carried by the valve member and being rotatable therewith, said locking ring being adapted to ride on the said end of the valve body and having its inner face formed with a fiat portion adapted to be turned to alignment with the flat face on the valve body when the valve is closed, the arrangement being such that the ring moves to engagement with the valve body by gravity.

5. In avalve for gas ranges, a valve body having an end formed with a flat side, a valve member rotatably mounted in the body and having a projecting end, a portion of which corresponds in form with the end of the valve body, a locking ring longitudinally movable on the valve member and having a part thereof fitting the said end portions of the valve member and further having a portion adapted to fit the said end of the valve body, the arrangement providing that when the ring is moved out of engagement with the valve body the valve member may be turned with the ring riding the end face of the body and when turned to closed position engages the body to hold the valve member from rotation.

In testimony whereof I sign this specification.
